Question

• I learn skywalking-python by this page: https://github.com/apache/skywalking-python
  after agent.start(),only create instance,but not track any request.
  when agent.start(), I also start my django server and request some api, then I view skywalking admin page,only see instance created but not trace any request info.

My fremework info:

• Python-3.7
• Djano-2.1.3
• skywalking-python-0.2.0

@shuguang-dong please set the logging level(config.logging_level) to DEBUG and paste your logs here

[kezhenxu94]

Perhaps you just hit the incompatibility of Django plugin, which is fixed in the master branch but not included in the 0.2.0, if possible, please try to build from the master branch codes and tell us whether it helps, or try a newer Django version (> 2.2), thanks

[shuguang-dong]

This is my code:

from skywalking import agent, config

config.init(
    service='shenlong-kol',
    instance='dev-local',
    collector='my sky walking address',
)
agent.start()

and I debug it in pycharm ,here is log:

sw_flask                         [MainThread     ] [WARNING ] failed to install plugin sw_flask
sw_kafka                         [MainThread     ] [WARNING ] failed to install plugin sw_kafka
sw_tornado                       [MainThread     ] [WARNING ] failed to install plugin sw_tornado

I will also try a newer Django version(>2.2) again

I tested Django==3.1, apache-skywalking==0.2.0. it worked well @shuguang-dong

import sys
import time

from skywalking import agent, config

from django.conf import settings
from django.conf.urls import url
from django.http import JsonResponse


config.service_name = "provider"
config.logging_level = "DEBUG"
agent.start()


settings.configure(
    DEBUG=True,
    ROOT_URLCONF=__name__,
    ALLOWED_HOSTS=['*'],
)


def index(request):
    time.sleep(0.5)
    return JsonResponse({"song": "Despacito", "artist": "Luis Fonsi"})


urlpatterns = (
    url("users", index),
)


if __name__ == "__main__":
    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

cmd: python3 test_django.py runserver 0.0.0.0:9090

I think the key may be this I will also try a newer Django version(>2.2) again

It's quite expected because we run the test cases over and over in the CI, and I'm pretty sure it's just a version incompatibility issue fixed by @Humbertzhang in apache/skywalking-python#52 in the master branch now(not included in the 0.2.0), I'll close this for now and if you @shuguang-dong have any further question, please comment here

@kezhenxu94 I think python agent should follow the java supported list doc style, add versions there.

@kezhenxu94 I think python agent should follow the java supported list doc style, add versions there.

Versioning the supported libraries as well as the tests is under construction by @Humbertzhang and I, will open another issue to track that
